nidicolous (adj.)

of birds, "bearing young which are helpless at birth," 1896, from Modern Latin Nidicolae (1894), the zoologists' collective name for the species of birds having the young born in a more or less helpless condition, unable to leave the nest for some time and fed directly by the parent, from Latin nidus "nest" (see nest (n.)) + colere "to inhabit" (see colony). Contrasted to nidifugous birds (1902), whose young are well-developed and leave the nest at birth (from Latin fugere "to flee").
